What's the best way to clear noise after applying the greenscreen effect?

I have increased the screen gain monumentally, but it seems to be doing very little...

If it's a generic green screen, I would avoid messing with the screen gain parameter completely. 

this could be a problem due to Keylight making the color correction, and introducing a lot of noise - it is notorious for doing that. to test if that's the case, set keylight to intermediate result. is the noise better? if so, to reduce the green spill, add the advanced spill suppressor effect.
